Oil and Gas exploration

Crude Oil and Natural Gas are fossil energy sources used for electricity generation, heating and fuel for transport purposes. Moreover they are important raw materials for manufacturing plastics and chemical products.

Microbial contamination may occur by proliferation of anaerobic bacteria, i.e. sulfate reducing bacteria (SRB), in oil and gas fields in pipelines, installations for oil and gas recovery and drilling as well as by the use of surface and seawater commonly used to increase process pressure.
